The present disclosure provides, in part, methods, computer programproducts systems, network devices, and virtual machine managementsoftware, for example, for controlling display of an image on a displayscreen. The technique of the present disclosure allows a user to readilyselect a target area of an image in a display for automatic display ofthe user selected target area on the display screen. The technique ofthe present disclosure may allow for quickly fitting a user selectedtarget area of an image into a full screen of a display screen, e.g.,automatically translate, zoom in, and/or zoom out of a user selectedtarget area of an image for display on the display screen. As describedbelow, the desired portion of the image for display on the displayscreen may include a portion of the image initially not displayed on thedisplay screen, or display of a portion of the image initially displayedon the display screen and a portion of the image initially not displayedon the display screen. The technique of the present disclosure mayprovide flexibility in showing the interested area as large as possibleon the display screen.

In addition, the technique of the present disclosure may only load anddisplay the user selected target area or portion of interest of theimage for subsequent display, and not the portion or portions of theimage disposed outside the boundary of the user selected target area,which may allow for more efficient and faster processing times of theuser selected target area for display.

FIGS. 1-4 depict various embodiments of computing, including cloudcomputing, in accordance with one or more embodiments set forth herein.

It is understood in advance that although this disclosure includes adetailed description on cloud computing, implementation of the teachingsrecited herein are not limited to a cloud computing environment. Rather,embodiments of the present invention are capable of being implemented inconjunction with any other type of computing environment now known orlater developed.

Cloud computing is a model of service delivery for enabling convenient,on-demand network access to a shared pool of configurable computingresources (e.g., networks, network bandwidth, servers, processing,memory, storage, applications, virtual machines, and services) that canbe rapidly provisioned and released with minimal management effort orinteraction with a provider of the service. This cloud model may includeat least five characteristics, at least three service models, and atleast four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provisioncomputing capabilities, such as server time and network storage, asneeded automatically without requiring human interaction with theservice's provider.

Broad network access: capabilities are available over a network andaccessed through standard mechanisms that promote use by heterogeneousthin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to servemultiple consumers using a multi-tenant model, with different physicaland virtual resources dynamically assigned and reassigned according todemand. There is a sense of location independence in that the consumergenerally has no control or knowledge over the exact location of theprovided resources but may be able to specify location at a higher levelof abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elasticallyprovisioned, in some cases automatically, to quickly scale out andrapidly released to quickly scale in. To the consumer, the capabilitiesavailable for provisioning often appear to be unlimited and can bepurchased in any quantity at any time.

Measured service: cloud systems automatically control and optimizeresource use by leveraging a metering capability at some level ofabstraction appropriate to the type of service (e.g., storage,processing, bandwidth, and active user accounts). Resource usage can bemonitored, controlled, and reported providing transparency for both theprovider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer isto use the provider's applications running on a cloud infrastructure.The applications are accessible from various client devices through athin client interface such as a web browser (e.g., web-based e-mail).The consumer does not manage or control the underlying cloudinfrastructure including network, servers, operating systems, storage,or even individual application capabilities, with the possible exceptionof limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer isto deploy onto the cloud infrastructure consumer-created or acquiredapplications created using programming languages and tools supported bythe provider. The consumer does not manage or control the underlyingcloud infrastructure including networks, servers, operating systems, orstorage, but has control over the deployed applications and possiblyapplication hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to theconsumer is to provision processing, storage, networks, and otherfundamental computing resources where the consumer is able to deploy andrun arbitrary software, which can include operating systems andapplications. The consumer does not manage or control the underlyingcloud infrastructure but has control over operating systems, storage,deployed applications, and possibly limited control of select networkingcomponents (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for anorganization. It may be managed by the organization or a third party andmay exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by severalorganizations and supports a specific community that has shared concerns(e.g., mission, security requirements, policy, and complianceconsiderations). It may be managed by the organizations or a third partyand may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the generalpublic or a large industry group and is owned by an organization sellingcloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or moreclouds (private, community, or public) that remain unique entities butare bound together by standardized or proprietary technology thatenables data and application portability (e.g., cloud bursting forload-balancing between clouds).

A cloud computing environment is service oriented with a focus onstatelessness, low coupling, modularity, and semantic interoperability.At the heart of cloud computing is an infrastructure comprising anetwork of interconnected nodes.

In the latter scenario,the remote computer may be connected to the user's computer through anytype of network, including a local area network (LAN) or a wide areanetwork (WAN), or the connection may be made to an external computer(for example, through the Internet using an Internet Service Provider).In some embodiments, electronic circuitry including, for example,programmable logic circuitry, field-programmable gate arrays (FPGA), orprogrammable logic arrays (PLA) may execute the computer readableprogram instructions by utilizing state information of the computerreadable program instructions to personalize the electronic circuitry,in order to perform embodiments of the present invention.

Embodiments of the present invention are described herein with referenceto flowchart illustrations and/or block diagrams of methods, apparatus(systems), and computer program products according to embodiments of theinvention. It will be understood that each block of the flowchartillustrations and/or block diagrams, and combinations of blocks in theflowchart illustrations and/or block diagrams, can be implemented bycomputer readable program instructions.

These computer readable program instructions may be provided to aprocessor of a general purpose computer, special purpose computer, orother programmable data processing apparatus to produce a machine, suchthat the instructions, which execute via the processor of the computeror other programmable data processing apparatus, create means forimplementing the functions/acts specified in the flowchart and/or blockdiagram block or blocks. These computer readable program instructionsmay also be stored in a computer readable storage medium that can directa computer, a programmable data processing apparatus, and/or otherdevices to function in a particular manner, such that the computerreadable storage medium having instructions stored therein comprises anarticle of manufacture including instructions which implementembodiments of the function/act specified in the flowchart and/or blockdiagram block or blocks.

The flowchart and block diagrams in the figures illustrate thearchitecture, functionality, and operation of possible implementationsof systems, methods, and computer program products according to variousembodiments of the present invention. In this regard, each block in theflowchart or block diagrams may represent a module, segment, or portionof instructions, which comprises one or more executable instructions forimplementing the specified logical function(s). In some alternativeimplementations, the functions noted in the block may occur out of theorder noted in the figures. For example, two blocks shown in successionmay, in fact, be executed substantially concurrently, or the blocks maysometimes be executed in the reverse order, depending upon thefunctionality involved. It will also be noted that each block of theblock diagrams and/or flowchart illustration, and combinations of blocksin the block diagrams and/or flowchart illustration, can be implementedby special purpose hardware-based systems that perform the specifiedfunctions or acts or carry out combinations of special purpose hardwareand computer instructions.

FIG. 5 is an exemplary block diagram of a system 500, in accordance withone or more embodiments set forth herein. For example, a network 150 maybe a physical network or a virtual network. A physical network can be,for example, a physical telecommunications network connecting numerouscomputer nodes or systems, such as computer servers and computerclients. By contrast a virtual network can, for example, combinenumerous physical networks or parts thereof into a logical virtualnetwork. In another example, numerous virtual networks can be definedover a single physical network.

By way of explanation, FIG. 5 depicts an example environment in whichone or more display control 100 may, for example, control display of animage on a display screen. In one example, display control 100 can be incommunication with one or more image database 110. As described ingreater detail below, display control 100 may be effective fordisplaying a portion of an image according to a user selected arearelative to an initial image disposed on a display screen. For example,the image database may be images of maps, map routes, photographs,computer-aided-design (CAD) drawings, or other images or data that maybe represented on a display screen. The one or more image database 110shown as being in communication via network 150 can alternatively beco-located at display control 100. For example, an electronic devicesuch as a hand held device such as a mobile phone, a smart phone, apersonal digital assistant (PDA), a tablet device, an internet device,or other electronic devices or products may include a display controland a screen display.

FIG. 6 illustrates a process, for example, for use in controllingdisplay of an image on a display screen in accordance with embodimentsof the present disclosure. By way of example, the processes describedwith respect to FIG. 6 can be performed using one or more program 440(FIG. 4) or one or more program 441 (FIG. 1) on one or more devicehaving display control 100 (FIG. 5), as detailed with respect to FIG. 4.

For example, one or more program 440 may include at 210, receiving, byone or more processor, data regarding a user selected area relative to afirst portion of an image displayed on a display screen to define asecond portion of the image, at least a portion of the second portion ofthe image being outside the first portion of the image displayed on thedisplay screen, and at 220 automatically controlling, by the one or moreprocessor, display of the second portion of the image on the displayscreen based on the user selected area of the image to maximize displayof the second portion of the image within the display screen.

FIGS. 7-11 diagrammatically illustrate user selected target areasrelative to an image and display of the user selected target areas of animage on the display screen of electronic device in accordance withembodiments of the present disclosure. For example, the display screenof the electronic device may initially display an image such as a map ormap route between a point A and B, and a user using the electronicdevice may select a portion of the map or map route for subsequentdisplay on the display screen, which selected portion may beautomatically displayed of the display screen.

In one example, as shown in FIG. 7, initially a first portion 342 of animage 340 may be displayed on a display screen 324. For example, image340 may be a map having roads and a map route illustrated between twopoints. A user may select a desired or target area 344 disposed withinthe displayed first portion 342 of image 340, such as using a camera orsmartband as described in greater detail below. For example, in someembodiments, a user may use his finger to trace the target area adjacentto the display screen such as the peripheral boundary or a portionsthereof of the target area such as shown by arrows C in FIG. 7. Thetrace may be a single continuous trace or a plurality of separatetraces. User selected target area 344 may be used for display of anenlarged or zoomed in second portion 346 of the image displayed ondisplay screen 324. For example, display screen 324 may be bounded by atop edge 332, a bottom edge 334, a left side edge 336, and a right sideedge 338. For example, the electronic device may include a rectangulardisplay screen, and a user selected area may be a rectangular area ofthe first portion of the image displayed on the display screen. Forexample, target area 344 may be bounded by a top edge 352, a bottom edge354, a right side edge 356, and a left side edge with 358. The userselected target area 344 may be used by one or more program 440 (FIG. 6)such as received at 210 (FIG. 6) and allow automatically controllingdisplay such as at 220 (FIG. 6) so that the size of the second portionof the image is maximized or zoomed in and translated to fit in thedisplay screen. The maximized second portion of the image may be basedon the orientation of the first portion of the image displayed to theuser and/or the orientation of the display screen.

In another example as shown in FIG. 8, initially a first portion 542 ofan image 540 may be displayed on a display screen 524. A user may selecta desired target area 544 disposed within the displayed first portion542 of image 540 such as using a camera or smartband as described ingreater detail below. For example, in some embodiments, a user may usehis finger to trace the target area adjacent to the display screen suchas the peripheral boundary or a portions thereof of the target area suchas shown by arrows D in FIG. 8. The trace may be a single continuoustrace or a plurality of separate traces. User selected target area 544may be used for display of an enlarged or zoomed in second portion 546of the image displayed on display screen 524. For example, theelectronic device may include a rectangular display screen, and a userselected area may be an oval area of the first portion of the imagedisplayed on the display screen. The user selected target area 544 maybe used by one or more program 440 (FIG. 6) such as received at 210(FIG. 6) and allow automatically controlling display such as at 220(FIG. 6) so that the size of the second portion of the image ismaximized or zoomed in and translated to fit in the display screen. Themaximized second portion of the image may be based on the orientation ofthe first portion of the image displayed to the user and/or theorientation of the display screen.

In another example as shown in FIG. 9, initially a first portion 642 ofan image 640 may be displayed on a display screen 624. A user may selecta desired target area 644 having a portion 643 which is disposed withinthe displayed first portion 642 of image 640, and a portion 645 of whichis disposed outside the displayed first portion 642 of image 640 such asusing a camera or smartband as described in greater detail below. Forexample, in some embodiments, a user may use his finger to trace thetarget area adjacent to the display screen such as the peripheralboundary or a portions thereof of the target area such as shown byarrows E in FIG. 9. The trace may be a single continuous trace or aplurality of separate traces. User selected target area 644 may be usedfor display of a second portion 646 of the image displayed on displayscreen 624. For example, the electronic device may include a rectangulardisplay screen, and a selected target area may be a generally squarearea. The user selected target area 644 may be used by one or moreprogram 440 (FIG. 6) such as received at 210 (FIG. 6) and allowautomatically controlling display such as at 220 (FIG. 6) so that thesize of the second portion of the image is maximized or zoomed out andtranslated to fit in the display screen. The maximized second portion ofthe image may be based on the orientation of the first portion of theimage displayed to the user and/or the orientation of the displayscreen.

In another example as shown in FIG. 10, initially a first portion 742 ofan image 740 may be displayed on a display screen 724. A user may selecta desired target area 744 having a portion of which corresponding tofirst portion 742, and a portion 745 of which is disposed outside thedisplayed first portion 742 of image 740 such as using a camera orsmartband as described in greater detail below. For example, in someembodiments, a user may use his finger to trace the target area adjacentto the display screen such as the peripheral boundary or a portionsthereof of the target area such as shown by arrows F in FIG. 10. Thetrace may be a single continuous trace or a plurality of separatetraces. User selected target area 744 may be used for display of asecond portion 746 of the image displayed on display screen 530. Forexample, the electronic device may include a rectangular display screen,and a selected area may be a generally rectangular area of the image.The user selected area 744 may be used by one or more program 440 (FIG.6) such as received at 210 (FIG. 6) and allow automatically controllingdisplay such as at 220 (FIG. 6) so that the size of the second portionis maximized, in this case zoomed out and translated to fit in thedisplay screen. The maximized second portion of the image may be basedon the orientation of the first portion of the image displayed to theuser and/or the orientation of the display screen.

In another example as shown in FIG. 11, initially a first portion 842 ofan image 840 may be displayed on a display screen 824. A user may selecta desired target area 844 which is disposed outside the displayed firstportion 842 of image 840 such as using a camera or smartband asdescribed in greater detail below. For example, in some embodiments, auser may use his finger to trace the target area adjacent to the displayscreen such as the peripheral boundary or a portions thereof of thetarget area such as shown by arrows G in FIG. 11. The trace may be asingle continuous trace or a plurality of separate traces. User selectedtarget area 844 may be used for display of a second portion 846 of theimage displayed on display screen 824. For example, the device mayinclude a rectangular display screen, and a selected area may be agenerally oval area of the image. The user selected area 844 may be usedby one or more program 440 (FIG. 6) such as received at 210 (FIG. 6) andallow automatically controlling display such as at 220 (FIG. 6) so thatthe size of the second portion is maximized, in this case zoomed out andtranslated to fit in the display screen. The maximized second portion ofthe image may be based on the orientation of the first portion of theimage displayed to the user and/or the orientation of the displayscreen. For example, in the event that the user turns the display, e.g.,turns a smartphone having the display, the second portion may bemaximized based on the orientation of the display screen, e.g.,providing a maximized second portion based on a screen displayorientated in a portrait view or landscape view. For example, rotatingthe electronic device 90 degrees may allow for the oval-shaped secondportion of the image to be enlarged in a landscape view of the displayscreen compared to the oval-shaped second portion of the image beingdisplayed in the portrait view of the display screen as illustrated inFIG. 11.

With reference again to FIGS. 7-11, it is noted that depending on theshape of the screen and the selected target area of interest, there maybe portions of the displayed image of the subsequent second imageportion that is not of interest or have non-related information. Forexample, the user selected area may be used by one or more program 440(FIG. 6) such as received at 210 (FIG. 6) and allow automaticallycontrolling display such as at 220 (FIG. 6) so that portions of theimage outside the second maximized and translated portion of the imageis not loaded. With reference still to FIGS. 7-11, a bottom portion 348(FIG. 7), corner portions 548 (FIG. 8), a portion 648 (FIG. 9), aportion 748 (FIG. 10), and a bottom portion 848 and corner portions 849(FIG. 11), may not be loaded and remain blank which may be moreefficient in allowing for faster processing and display of theinterested portions of the image, as well as being less distracting tothe user. While the second portions of the image are illustrated asbeing disposed closer to the top of the screen display, the secondportions may be disposed in the middle or on other areas of the displayscreen. From the present description, it will be appreciated that insome embodiments, data regarding the image, the first portion of theimage, and the second portion of the image for display on the displayscreen may be contained in the electronic device, contained on cloudcomputing environment 50 (FIG. 2), or a combination thereof.

FIG. 12 illustrates another process, for example, for use in controllingdisplay of an image on a display screen in accordance with embodimentsof the present disclosure. By way of example, the processes describedwith respect to FIG. 12 can be performed using one or more program 440(FIG. 4) on one or more device having display control 100 (FIG. 5), asdetailed with respect to FIG. 4.

For example, one or more program 440 may include at 910, capturing orreceiving a user selected target area having arbitrary boundaries. Ifthe boundaries of the selected target area of the image are all on thedisplay screen, the target area recognition module recognized the areaas the target area. If any boundary of the selected target area is outof the screen, the target area recognition module is used to decide theboundaries of the virtual part to complete the target area. After theboundaries of the selected area are determined, including physicalboundaries on the screen and virtual boundaries out of the screen, at920, the shape of the user selected area is coordinated such as trimmedto the display screen, for example to the height-width ratio of thedisplay screen so that a second portion of the image corresponding tothe selected target area is maximized to fit in the display screen. At930, the second portion is zoomed in or out and/or translated so that itmay be fully displayed on the display screen.

With reference again to FIG. 4, in one embodiment, input/output device22 or external devices 14 may include one or more cameras for receivinginput or data from a user regarding the selected target area such assize and position relative to the display screen.

For example, one or more cameras may be employed to track a user's handmovement in the air when selecting the target area. A front cameraand/or a rear camera on the electronic device may be used for capturingthe user's movement, e.g., desirably with the users and movement notbeing exactly on the same 2D plane of the electronic device or thedisplay screen. A wide-angle or even super wide-angle camera can capturea 170 degree or a 180 degree range, e.g., Fish Fisheye Lens 180 DegreeSuper Wide Angle for IPhone 6, Samsung S5, or Note. In this way, theuser's movement may be captured even if it is on the same plane of theelectronic device. Existing technologies may be employed for detectingand recording the trace of a user's hand movement. For example, a usermoving one's hand may be detected from a background and its movementtracked by using image recognition technologies on a pixel level. Othertechnologies include, e.g., tracking an object from a live video input.

FIG. 13 illustrates another process, for example, for use in controllingdisplay of an image on a display screen in accordance with embodimentsof the present disclosure. By way of example, the processes describedwith respect to FIG. 13 can be performed using one or more program 440(FIG. 4) on one or more device having display control 100 (FIG. 5), asdetailed with respect to FIG. 4.

For example, one or more program 440 may include at 1010, capturing theshape and the size of the selected target area, and at 1020, obtainingthe relative position of the selected target area to the screen displayof the electronic device. At 1030, the selected target area is used tolocate the corresponding portion of the image. At 1040, the shape andside of the corresponding portions of the image is accommodated, e.g.,translated, zoomed in, and/or zoomed out, to fit or maximize the viewingon the display screen.

When a trace of a user's movement of the selected target area isrecorded, the size of the selected target area bounded by or encircledby the trace may be calculated by using the focal length of the camera,the image size of this area generated by the camera, and the imagedistance of this imaging. For example, with reference again to FIG. 4,in another embodiment, external device 14 may include one or morecameras for receiving input or data from a user regarding the selectedtarget area such as size and position relative to the display screen.

For example, with reference to FIG. 14, a calculation for use indetermining the user selected target area may be as follows, where h_(o)is the actual object height, h_(i) is the imaged object height, m is themagnification ratio, f is the camera's focal length, and v is the imagedistance between the lens plane and the image plane. From the followingtwo equations:

m=hi/ho; and

m=(v/f)−1=(v−f)/f

the actual height of the object can be worked out as:

h _(o) =h _(i) /m=h _(i) *f/(v−f)

Similarly, based on the mirroring relationship between the user selectedtarget area and its image behind the lens as shown in FIG. 14, therelative position of the selected target area and the lens (or theelectronic device) can be calculated from the relative position of theimage and the lens.

With reference to FIGS. 15 and 16, and based on the size of the selectedtarget area and its relative position to the electronic device, a2-dimensional coordinate system may be used for acquiring the secondportion of the image that is desired to be select from the image. Asshown in FIG. 14, an image 1140 and user selected target area 1144represents the virtual selected target area selected by the user. Thecenter of the screen may be used as the central point of the2-dimensional coordinate system for locating and positioning theelements based on the shape and location data as determined above. Then,the size of this selected target area is adjusted or mapped to, forexample, the largest size that can fit the full screen of the displayscreen as shown in FIG. 16.

With reference again to FIG. 4, in another embodiment, external device14 may include a wearable device such as a smartband for receiving inputor data from a user regarding the selected target area such as size andposition relative to the display screen.

For example, the smartband may be a wristwatch-type input device thatrecognizes human hand gestures by capacitively measuring wrist-shapechanges and also measuring forearm movements. The device may include twoinput sensors (capacitance and acceleration sensors), and one tactilefeedback actuator. The device may recognize hand gestures by measuringthe changes of the arm shape on the inside of the wrist-band using acombination of transmitter and receiver electrodes attached to the backof the watch dial and inside of the wristband. This combination may actsas a capacitance sensor. In addition to the hand-shape measurement, anacceleration sensor (Analog Devices ADXL202) may be mounted on thewristwatch dial. The acceleration sensor may be a solid-state 2-axissensor for measuring the inclination of the forearm. By recording datacollected by capacitance and acceleration sensors, hand movement can beused to obtain a trace a user selected target area. By using thepositioning sensors in smartband and the electronic device, the relativesize and position of the traced selected target area may be obtained.Then, the selected virtual area may be mapped to the full screen of thedisplay.

With reference still to FIG. 4, in other embodiment, display 24 andexternal device 14 may be one or more cameras, smartbands, eye trackingdevices, or other suitable devices, and combinations thereof forreceiving input or data from a user regarding the selected target areawhich may be processed in accordance with embodiments of the presentdisclosure.

FIG. 17 is a diagram illustrating further processes, for example, forcontrolling display of an image on a display screen in accordance withone or more embodiments set forth herein. By way of explanation, in FIG.17, processes are illustrated from the point of view of an imagedatabase 110 (e.g., such as image database 24 of FIG. 5), displaycontrol one or more programs 440 (e.g., display control one or moreprograms 440 or 441 running on display control 100 of FIG. 5), a display24 (e.g., display 24 of FIG. 4), and a user 120. User 120 can refer to ahuman user of a user interface of the one or more program 440. A userinterface may include one or more cameras, smartbands.

In one or more embodiments, one or more program 440 may run on adifferent collection of physical or virtual machines or processors,depending on the need for scalability of the system. In one specificexample, one or more program 440 could run on a single multi-processorserver system. In another specific example, various portions of one ormore program 440 may run on different processors running on differentcomputing nodes.

By way of overview, FIG. 17 illustrates, at least in part, one or moreembodiments for controlling display of an image on a display screen. Itwill be understood that based on a different set or order of user inputsone or more program 440 can provide different functionality than thefunctionality described with reference to FIG. 17.

Initially a user may send at block 1200 a request for an image to imagedatabase 110, which request is received at block 1210. Image database110 may send at block 1220 an image which is displayed on display 24 atblock 1230.

In one embodiment, a user viewing the display on the image on a displayscreen, may input a selected target area relative to the image displayedon the display at block 1300 such as explained above. At block 1310,display control one or more program 440 may receive the inputtedselected target area. Display control one or more program 440 may atblock 1320 send data regarding display of the image to display 24 suchas data for resizing and/or translating the display of the image asdescribed above, which is implemented at block 1330 on display 24. Theprocess may be repeated by the user for further viewing of portions ofthe image.

In another embodiment, a user viewing the display on the image on adisplay screen, may input a selected target area relative to the imagedisplayed on the display at block 1300 such as explained above. At block1310, display control one or more program 440 may receive the inputtedselected target area. Display control one or more program 440 may atblock 1340 send a request for a resized and/or a translated image toimage database 110, which is received at image database 110 at block1350. At block 1360, the resized and/or a translated image is sent todisplay 24 for display for viewing by the user at block 1370. Theprocess may be repeated by the user for further viewing of portions ofthe image.

From the present description, it will be appreciated that techniques ofthe present disclosure allow a user selected target area of an image forenlargement that may be any shape and any size, and when a displaycontrol process or a smart full screen operation is performed, theselected area may be automatically enlarged/reduced and fitted onto thescreen. For example, the selected area may be enlarged as much aspossible based on the size of the display, e.g., one or more sideportions of the selected area being moved to one or more side edges ofthe display screen.

As described above, the technique of the present disclosure may allow auser to quickly fit a desired selected area on a screen or out of thescreen into a full screen display. Benefits of the present technique mayinclude the selected area being of any shape, so that the screen wouldbe used sufficiently to display that portion of an image of interest.The selected area may include a portion of the image that is initiallyout of view of the screen. A partial loading operation of only theportions of the image corresponding to the user's selected target areamay be more efficient since only the interested part of the image isloaded.
